[Help] Dropdown menu as program arguments

I'm new to VB.Net programming, so I decided to make a small app that runs another app with arguments.
I think the best way to do it was selecting one option from a dropdown menu and using this option as an argument to run the app.

'you could have a mnuItem and set the arg to
'its text property or its tag.
'Theres all kinds of ways.
'This item has c:\scrap.bmp for its text, which will open
'that image in mspaint
Process.Start("Mspaint.exe", mnuArgs_Arg1.Text)
'fixed size border style
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.FixedSingle
'disable menu
mnuArgs.Enabled = False
'or
mnuArgs_Arg1.Enabled = False

Process.Start("Mspaint.exe", mnuArgs_Arg1.Text)

Me.FormBorderStyle = Windows.Forms.FormBorderStyle.FixedSingle
'disable menu
mnuArgs.Enabled = False

mnuArgs_Arg1.Enabled = False

Thanks! And sorry for the late response, I had to go to work.
I didn't get the part or the arguments... I thought on something like... user select a item from the dropdown menu and that changes the value of a variable, which will be the parameter. Something like this:

User select option 1. Option 1 changes the value of the variable 1 to x.
If user select option 2 later, it will change again the value of variable, but this time to y.

And so on.

The part of resize was Ok, worked fine! Thank you!

I found a "workaround" to make the dropdown to not act like a text box: changed dropdown style in properties pane to DropDownList instead just DropDown. That did the trick.

Can you or someone else explain me a little more the arguments part?
Thanks in advance!

Of course, the path of your .exe's application should be edited for the above code to work.

Also, if you create a Shortcut for your .exe application that has Argument(s) options, right click the Shortcut, select Properties, and modify the "Target" textbox to contain a blank space and your argument.

Now I wish to improve the code, add more options. How can I make a checkbox functional? And how can I make a group of radio buttons functional too?

If I use more than one checkbox to have arguments, how I add it to Process.Start? I mean... more than one option, more than one argument. I thought on creating a variable that will hold all arguments, and use this variable to pass the arguments. Is this right?
